[0002] The four-way shuttle is an intelligent shuttle handling equipment that integrates four-way travel, on-site track change, automatic handling, intelligent monitoring and dynamic traffic management.

[0030] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0031] Figure 1The structure of a four-way shuttle with closed transmission in one embodiment of the utility model is shown. For ease of description, the accompanying drawings only show structures related to the embodiment of the utility model.

[0032] See also Figures 1 to 3 The enclosed transmission four-way shuttle 100 in the preferred embodiment of the utility model includes a vehicle body 110, two transverse walking mechanisms 120, two longitudinal walking mechanisms 130, a walking power assembly 140 and two reversing lifting mechanisms 150.

[0033] The vehicle body 110 includes a bottom plate 111, two transverse side plate structures 112, two longitudinal side plate structures 113 and two reversing side plate structures 114. The two transverse side plate structures 112 are arranged on the bottom plate 111 at intervals. The two longitudinal side plate structures 113 are arranged on the bottom plate 111 at intervals, and each longitudinal side plate structure 113 is connected between the two transverse side plate structures 112. In this way, in the circumferential direction of the bottom plate 111, the two transverse side plate structures 112 and the two longitudinal side plate structures 113 are alternately connected in sequence to enclose the vehicle body 110 of a hollow box structure together with the bottom plate 111. The two reversing side plate structures 114 are slidably mounted on the outer sides of the two longitudinal side plate structures 113, respectively.

[0034] The two transverse traveling mechanisms 120 correspond to the two transverse side plate structures 112. The transverse traveling mechanisms 120 include transverse wheels 121 disposed on the corresponding transverse side plate structures 112 and transverse transmission components 122 (not shown) connected to the transverse wheels 121.

[0035] The two longitudinal running mechanisms 130 correspond to the two reversing side plate structures 114 one by one. The longitudinal running mechanisms 130 include longitudinal driving wheels 131 and longitudinal driven wheels 132 arranged on the corresponding reversing side plate structures 114.

[0036] The travel power assembly 140 is respectively connected to the transverse transmission assembly 122 and the longitudinal driving wheel 131. The travel power assembly 140 is arranged in the vehicle body 110, and is used to drive the longitudinal driving wheel 131 to rotate and drive the transverse wheel 121 to rotate through the transverse transmission assembly 122, so as to achieve the purpose of driving the vehicle body 110 to travel on the transverse track or the longitudinal track.

[0037] The two reversing lifting mechanisms 150 correspond to the two reversing side plate structures 114 one by one. The reversing lifting mechanism 150 includes a reversing lifting assembly 151 (not shown) connected to the corresponding reversing side plate structure 114, a reversing transmission assembly (not shown) connected to the reversing lifting assembly 151, and a reversing power assembly 152 connected to the reversing transmission assembly. Among them, the structures of the transverse transmission assembly 122 and the reversing transmission assembly can be the same or different, and their specific form is a common transmission structure in the prior art, specifically a chain transmission assembly and the like; the reversing lifting assembly 151 is a conventional structure in the existing four-way shuttle, and will not be described in detail here.

[0038] The reversing power assembly 152 is in transmission connection with the reversing transmission assembly. The reversing power assembly 152 is used to drive the reversing side plate structure 114 through the reversing transmission assembly to drive the longitudinal driving wheel 131 and the longitudinal driven wheel 132 to rise and fall, so as to ensure that the driving direction of the closed transmission four-way shuttle 100 is switched between the transverse track direction and the longitudinal track direction, so as to achieve the purpose of free reversal. Specifically, the reversing power assembly 152 is installed in the vehicle body 110.

[0039] Among them, the transverse side plate structure 112 is a double-layer structure with a transverse transmission cavity 1121, and the longitudinal side plate structure 113 is a double-layer structure with a reversing transmission cavity (not shown in the figure). The transverse transmission component 122 and the reversing transmission component are respectively installed in the transverse transmission cavity 1121 and the reversing transmission cavity.

[0040] Specifically, when the reversing side plate structure 114 drives the longitudinal driving wheel 131 and the longitudinal driven wheel 132 to rise until the transverse wheel 121 contacts the transverse track, the longitudinal driving wheel 131 and the longitudinal driven wheel 132 are both suspended, and the driving direction of the closed-type transmission four-way shuttle 100 is switched from the longitudinal track direction to the transverse track direction; when the reversing side plate structure 114 drives the longitudinal driving wheel 131 and the longitudinal driven wheel 132 to descend until they contact the longitudinal track, the transverse wheel 121 is suspended, and the driving direction of the closed-type transmission four-way shuttle 100 is switched from the transverse track direction to the longitudinal track direction. That is, under the power provided by the reversing power assembly 152, the reversing lifting mechanism 150 operates to drive the reversing side plate structure 114 to rise and fall, thereby realizing the automatic switching of the driving direction of the closed-type transmission four-way shuttle 100.

[0041] Specifically, the reversing side plate structure 114 can slide relative to the longitudinal side plate structure 113 in a direction perpendicular to the bottom plate 111. Of course, in other embodiments, the sliding direction of the reversing side plate structure 114 can also slightly deviate from the direction perpendicular to the bottom plate 111, as long as the height of the longitudinal driving wheel 131 and the longitudinal driven wheel 132 can be driven to change.

[0042] It should be noted that, in the above-mentioned transverse side panel structure 112, longitudinal side panel structure 113, transverse running mechanism 120, longitudinal running mechanism 130, transverse guide rail and longitudinal guide rail, the transverse and longitudinal directions are only for distinguishing the side walls in different directions on the vehicle body 110, distinguishing the running mechanisms in two directions, and distinguishing the guide rails that are staggered and in different directions, so as to facilitate the correspondence of the side panel structures, running mechanisms and guide rails in the same direction, and it is not a limitation of the transverse and longitudinal directions in the conventional sense.

[0043] In the above-mentioned four-way shuttle vehicle 100 with closed transmission, the transverse side plate structure 112 and the longitudinal side plate structure 113 are both set as double-layer structures, so that the side walls of the vehicle body 110 are all double-layer structures, thereby improving the side wall strength of the vehicle body 110. At the same time, the transverse transmission component 122 and the reversing transmission component are respectively installed in the transverse transmission cavity 1121 and the reversing transmission cavity, that is, the transverse transmission component 122 and the reversing transmission component are respectively enclosed in the transverse side plate structure 112 and the longitudinal side plate structure 113, which can not only reduce the pollution of the transverse transmission component 122 and the reversing transmission component by external dust, impurities, water, etc., reduce the probability of overhaul and maintenance of the transverse transmission component 122 and the reversing transmission component, which is conducive to extending the service life and reducing the overhaul and maintenance cost, but also reduce the operating noise of the transverse transmission component 122 and the reversing transmission component. Therefore, the above-mentioned four-way shuttle vehicle 100 with closed transmission has the advantages of high structural strength, low noise, long service life, and low overhaul and maintenance cost.

[0044] In some embodiments, an inspection opening 1122 communicating with the transverse transmission cavity 1121 is formed at one end of the transverse side plate structure 112 away from the top plate. The vehicle body 110 further includes an inspection panel 116 detachably mounted at the inspection opening 1122.

[0045] In actual application, the inspection panel 116 can be removed to open the inspection opening 1122, so that the staff can check the condition of the transverse transmission assembly 122 in the transverse transmission cavity 1121 and inspect and maintain the transverse transmission assembly 122. The inspection panel 116 can also be covered on the inspection opening 1122 to seal the transverse transmission cavity 1121, thereby achieving the purpose of dust prevention. Therefore, the provision of the inspection panel 116 and the inspection opening 1122 greatly improves the convenience of use of the closed transmission four-way shuttle 100.

[0046] Specifically, there are multiple inspection openings 1122 and inspection panels 116 in a one-to-one correspondence. Multiple inspection openings 1122 are arranged at intervals along the travel direction of the transverse traveling wheels 121. The arrangement of multiple inspection openings 1122 and multiple inspection panels 116 facilitates the staff to observe the condition of the transverse transmission assembly 122 at different positions of the longitudinal side plate structure 113 and to inspect and maintain the transverse transmission assembly 122, further improving the convenience of use of the closed transmission four-way shuttle 100.

[0047] In some embodiments, the longitudinal side plate structure 113 includes a supporting side plate 1131 and an inner side plate 1132. A mounting groove (not shown) is formed on one side surface of the inner side plate 1132. The supporting side plate 1131 is detachably mounted on the inner side plate 1132, so that the surface of the supporting side plate 1131 and the inner wall of the mounting groove form a reversing transmission cavity. The two ends of the supporting side plate 1131 are respectively fixedly connected to the two adjacent transverse side plate structures 112. The reversing side plate structure 114 is slidably mounted on the side of the supporting side plate 1131 away from the inner side plate 1132.

[0048] The inner plate 1132 may be an integrally formed structure obtained by machining, 3D printing, etc., or a shell structure formed by fixing a plurality of plates together by welding, etc. The inner plate 1132 is detachably mounted on the inner side of the supporting side plate 1131 to facilitate disassembly, assembly, inspection and maintenance of the reversing rotating assembly and other parts in the reversing transmission cavity.

[0049] Furthermore, in some embodiments, the ends of both ends of the inner side plate 1132 are spaced apart from the adjacent transverse side plate structure 112. Both ends of the supporting side plate 1131 are provided with a long strip through hole 11311 in a direction perpendicular to the bottom plate 111, and the long strip through hole 11311 is located in the gap between the inner side plate 1132 and the transverse side plate structure 112. The axles of the longitudinal driving wheel 131 and the longitudinal driven wheel 132 are movably arranged in the long strip through hole 11311, and extend into the inner side of the longitudinal side plate structure 113. The travel power assembly 140 is connected to the axle of the longitudinal driving wheel 131 through a telescopic coupling.

[0050] In this way, the travel power assembly 140 is installed on the bottom plate 111 in the vehicle body 110, and is connected to the axle of the longitudinal driving wheel 131 passing through the long strip through hole 11311 through the telescopic coupling, which is conducive to a more compact structure of the closed transmission four-way shuttle 100. The arrangement of the long strip through hole 11311 facilitates the longitudinal driving wheel 131 and the longitudinal driven wheel 132 to rise and fall relative to the longitudinal side plate structure 113 during the reversing process of the closed transmission structure four-way shuttle 100.

[0051] Further, in some embodiments, guide blocks 1133 are fixed at both ends of the supporting side plate 1131. Each guide block 1133 has a sliding portion (not marked in the figure) on the side facing the other guide block 1133. Both ends of the reversing side plate structure 114 have a matching portion (not marked in the figure). The sliding portion and the matching portion can be slidably matched, and the sliding direction is perpendicular to the bottom plate 111.

[0052] The sliding part and the corresponding matching part can be slidably matched to each other so as to slidably connect one end of the reversing side plate with the guide block 1133, thereby realizing the slidable connection between the reversing side plate and the supporting side plate 1131, and guiding the lifting direction of the reversing side plate to ensure the reversing of the closed transmission four-way shuttle 100.

[0053] Furthermore, in some embodiments, one of the sliding portion and the matching portion is provided with a slide groove, and the other is provided with a slide rail structure matching the slide groove. The slide groove can be a V-shaped groove, a rectangular groove, a trapezoidal groove, etc. Specifically in this embodiment, the slide groove is a trapezoidal groove.

[0054] When a slide groove as a sliding part is formed on the guide block 1133, a slide rail structure as a matching part is formed on the end of the reversing side plate; when a slide rail structure as a sliding part is formed on the guide block 1133, a slide groove as a matching part is formed on the end of the reversing side plate. The slide groove is set on one of the sliding part and the matching part, and the slide rail structure is set on the other to facilitate the installation work between the reversing side plate and the guide block 1133.

[0055] Specifically, a trapezoidal groove serving as a sliding portion is formed on one side of each guide block 1133 facing the other guide block 1133 , and trapezoidal slide rails serving as a matching portion are formed on both ends of the reversing side plate.

[0056] In some embodiments, the travel power assembly 140 includes a travel motor reducer (not shown), a travel transmission shaft 141 and two telescopic couplings (not shown). The two ends of the travel transmission shaft 141 are rotatably disposed on the two lateral side plate structures 112 and extend outward from the lateral side plate structures 112. The two ends of the travel transmission shaft 141 are respectively connected to the two lateral transmission assemblies 122. The travel motor reducer is connected to the travel transmission shaft 141. The two ends of each telescopic coupling are respectively connected to the travel motor reducer and the axle of the corresponding longitudinal driving wheel 131.

[0057] In this way, each end of the travel transmission shaft 141 passes through the transverse transmission cavity 1121 and extends out of the transverse side plate structure 112, so that each end of the travel transmission shaft 141 is rotatably connected to the two side walls of the transverse side plate structure 112, so each end of the travel transmission shaft 141 is supported at two points, so that the transverse side plate structure 112 has a better support effect on the travel transmission shaft 141, and at the same time, the transmission of the travel power assembly 140 is more stable. The setting of the telescopic coupling facilitates the power transmission between the travel motor reducer and the lateral driving wheel during the lifting and lowering process of the reversing side plate.

[0058] In some embodiments, the reversing power assembly 152 includes a reversing transmission shaft 1521 and a reversing motor reducer (not shown). The two ends of the reversing transmission shaft 1521 are rotatably disposed on the two longitudinal side plate structures 113 and extend to the outside of the longitudinal side plate structures 113. The reversing motor reducer is in transmission connection with the reversing transmission shaft 1521. The two ends of the reversing transmission shaft 1521 are in transmission connection with the two reversing transmission components.

[0059] Therefore, each end of the reversing transmission shaft 1521 passes through the reversing transmission cavity to reach the outside of the longitudinal side plate structure 113, so that each end of the reversing transmission shaft 1521 is respectively rotatably connected to the two side walls of the longitudinal side plate structure 113. Therefore, each end of the reversing transmission shaft 1521 achieves two-point support, so that the longitudinal side plate structure 113 has a better support effect on the reversing transmission shaft 1521, and at the same time makes the transmission of the reversing power assembly 152 more stable.

[0060] Specifically, when the longitudinal side plate structure 113 includes the supporting side plate 1131 and the inner side plate 1132 , each end of the reversing transmission shaft 1521 is rotatably connected to the supporting side plate 1131 and the inner side plate 1132 , respectively.

[0061] In some embodiments, the closed transmission four-way shuttle 100 further includes a two-dimensional code blowing device 160. The two-dimensional code blowing device 160 is configured to blow and clean the positioning two-dimensional code regularly. The setting of the two-dimensional code blowing device 160 can blow the positioning two-dimensional code regularly to automatically and timely remove the dust covering the positioning two-dimensional code, so as to ensure accurate acquisition of the information on the positioning two-dimensional code, facilitate positioning the moving position of the closed transmission four-way shuttle 100, and improve the reliability and convenience of the use of the closed transmission four-way shuttle 100.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
